Textbook Question

Chapter 3, Problem 1Q

One car travels due east at 40 km/h. and a second car travels north al 40 km/h. Arc their velocities equal? Explain.

Expert Solution & Answer

To determine

Whether the velocities of the cars are equal or not.

Answer to Problem 1Q

The velocities of the cars are not equal since their direction of motion are different.

Explanation of Solution

Velocity is a vector quantity. It have both magnitude and direction. If two objects are said to be moving with same velocity, they must have same speed (magnitude of velocity) and they must be moving in the same direction.

In the given situation, one car is moving at 40 km/h towards east and the other car is moving at 40 km/h towards north. Even though both the cars are moving with same speed, their direction of motion are different. Therefore, the velocities of the cars are not equal.

Imagine you are out for a stroll on a sunny day when you encounter a lake. Unpolarized light from the sun is reflected off the lake into your eyes. However, you notice when you put on your vertically polarized sunglasses, the light reflected off the lake no longer reaches your eyes. What is the angle between the unpolarized light and the surface of the water, in degrees, measured from the horizontal? You may assume the index of refraction of air is nair=1 and the index of refraction of water is nwater=1.33 . Round your answer to three significant figures. Just enter the number, nothing else.
